A method performed by a wireless device (410) includes transmitting an uplink, UL, burst to a network node (460). The UL burst includes UL control information, UCI, multiplexed in a Physical Uplink Shared Channel, PUSCH. The UCI carries one or more parameters for unlicensed operation, and the UL burst has an associated UL burst structure. The UL burst structure includes a first slot, a full slot, and a last slot.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
2. The method of claim 1, wherein the first slot comprises one or more mini slots and Type B scheduling is used for PUSCH transmission within the first slot.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the first slot of the UL burst is made up of one or more mini-slots, and Type B scheduling is specifically used for PUSCH transmissions within this first slot.
3. The method of claim 1, wherein the first slot and/or the last slot is the full slot.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the first slot, the last slot, or both can be configured to be the full slot within the UL burst structure.
4. The method of claim 1, wherein a PUSCH transmission occupies less than all of the last slot.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the PUSCH transmission, which carries the UCI, occupies only a portion of the last slot, meaning it does not fill the entire last slot.
5. The method of claim 1 comprising receiving a configuration for one or more ending positions that apply to the last slot of the UL burst.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. As part of this method, the wireless device receives a configuration from the network node that defines one or more specific ending positions for the last slot of the UL burst.
8. The method of claim 1, wherein the pattern for the one or more demodulation reference signals is indicative of an associated mapping for a location of the UCI.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the specific pattern of the one or more demodulation reference signals (DMRS) transmitted within the UL burst serves to indicate how and where the UCI is mapped or located within the PUSCH.
9. The method of claim 1, wherein each pattern of one or more demodulation reference signals associated with each of the first slot, the full slot, and the last slot is the same.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the pattern for the one or more demodulation reference signals (DMRS) is kept consistent; specifically, the DMRS pattern associated with the first slot, the full slot, and the last slot is identical across all three parts of the UL burst.
12. The method of claim 11, wherein the first slot comprises one or more mini slots.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the first slot of the UL burst is composed of one or more mini-slots.
13. The method of claim 11, wherein the first slot and/or the last slot is the full slot.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, either the first slot, the last slot, or both can be configured to be the full slot within the UL burst structure.
14. The method of claim 11, wherein a PUSCH transmission occupies less than all of the last slot.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the PUSCH transmission, which carries the UCI, occupies only a fraction of the last slot, meaning it does not fill the entire last slot.
15. The method of claim 11, further comprising transmitting a configuration for one or more ending positions that apply to the last slot of the UL burst.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. As part of this method, the wireless device further transmits a configuration that specifies one or more ending positions applicable to the last slot of the UL burst. This allows the device to propose or define how the burst ends.
17. The method of claim 11, wherein the pattern for the one or more demodulation reference signals is indicative of an associated mapping for a location of the UCI, and the method further comprises mapping the UCI to the PUSCH.
A wireless device transmits an Uplink (UL) burst to a network node. This UL burst carries Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. In this method, the pattern of the one or more demodulation reference signals (DMRS) indicates the associated mapping for the UCI's location. The wireless device explicitly maps the UCI into the PUSCH according to this indicated mapping.
20. The method of claim 19, further comprising performing blind detection for UCI presence in a next symbol after each demodulation reference signal symbol in each mini-slot.
A network node receives an Uplink (UL) burst from a wireless device. This UL burst contains Uplink Control Information (UCI) that specifies parameters for unlicensed operation, multiplexed within a Physical Uplink Shared Channel (PUSCH). The UL burst has a structure including a first slot, a full slot, and a last slot. To find the UCI within this received burst, the network node performs blind detection. This means it specifically searches for UCI presence in the symbol immediately following each demodulation reference signal (DMRS) symbol, within every mini-slot present in the burst.
